This 3 inch original 1967-68 ABA (American Basketball Association) Denver Rockets patch is in beautiful condition.  The Ringsby System is printed on the bottom of this patch because the team was named for owner Bill Ringsby’s “Ringsby Rocket Trucking System and it was only used the first year.  This beautiful red, black, and white patch is rare and has been in the family for years, I think I got it from one of my grandfathers.
